## Abstract A natural digraph analog of the graph theoretic concept of β€œan independent set” is that of β€œan acyclic set of vertices,” namely a set not spanning a directed cycle. By this token, an analog of the notion of coloring of a graph is that of decomposition of a digraph into acyclic sets. We

A 2-coloring (G 1 , G 2 ) of a digraph is 2-primitive if there exist nonnegative integers h and k with h + k > 0 such that for each ordered pair (u, v) of vertices there exists an is the minimum value of h + k taken over all such h and k. In this paper, we consider 2-colorings of strongly connected
